[0001] The utility model belongs to the technical field of dust suppression devices, and in particular relates to a lifting dust-blocking curtain. Background Art

[0002] Coal transportation mostly adopts belt conveyor, which is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of a frame, a conveyor belt, rollers, a roller, a tensioning device and a transmission device. The belt conveyor forms a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. Because the belt conveyor has a strong conveying capacity, a long conveying distance, a simple structure and easy maintenance, it can easily implement programmed control and automatic operation; therefore, the belt conveyor is widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food, etc., and is suitable for the assembly, testing, debugging, packaging and transportation of objects.

[0003] In order to prevent the coal on the conveyor belt from leaking to both sides due to being too high, a coal scraper is generally installed above the coal conveyor. However, the existing coal scraper has the disadvantage of being inconvenient to adjust the height, and the coal is easy to generate dust when hitting the coal scraper, causing pollution to the working environment. Therefore, it is urgent to design a lifting dust curtain to solve the above problems. Utility Model Content

[0023] The utility model provides Figure 1-3 A lifting dust curtain as shown in the figure comprises:

[0024] A mounting plate 100, with mounting holes 101 arranged around the mounting plate 100, and a connecting seat 102 fixed to the lower surface of the mounting plate 100;

[0025] The lifting mechanism 200 includes a screw rod 201, a nut seat 202, an upper lifting rod 203, a lower lifting rod 204 and a connecting rod 205. The nut seat 202 is threadedly connected to the screw rod 201. One end of the upper lifting rod 203 and the lower lifting rod 204 are both hinged to one side of the nut seat 202. The other end of the upper lifting rod 203 is hinged to the connecting seat 102. A connecting seat 2051 is fixed to the upper surface of the connecting rod 205. The other end of the lower lifting rod 204 is hinged to the connecting seat 2051.

[0026] The dust-proof curtain 300 includes a fixed clamping plate 301 and a dust-reducing rubber strip 302 . The fixed clamping plate 301 is fixedly connected to the bottom of the connecting rod 205 , and one end of the dust-reducing rubber strip 302 is fixed inside the fixed clamping plate 301 .

[0027] In addition, the mounting plate 100 is fixed directly above the coal conveyor by bolts, so that the height of the dust curtain 300 can be adjusted by the lifting mechanism 200, and the coal on the conveyor belt that is higher than the set value can be scraped off by the dust curtain 300.

[0028] Specifically, the screw 201 is respectively provided with a positive thread 2011 and a negative thread 2012. When the screw 201 rotates, it can drive the two nut seats 202 on the screw 201 to move towards or in the opposite directions. Both ends of the positive thread 2011 and the negative thread 2012 are provided with limit blocks 2013, which can limit the movement stroke of the nut seat 202.

[0029] It is worth mentioning that there are four upper lifting rods 203 and four lower lifting rods 204, and the lengths of the upper lifting rods 203 and the lower lifting rods 204 are the same. The two upper lifting rods 203 and the two lower lifting rods 204 located on the same side can limit the nut seat 202 on that side so that it cannot rotate together with the screw 201. When the screw 201 rotates, the nut seat 202 on that side will move in a straight line. The movement principles of the two nut seats 202 are the same, and they jointly drive the upper lifting rod 203 and the lower lifting rod 204 to move toward or in the opposite direction, thereby realizing the lifting and lowering adjustment of the dust curtain 300.

[0030] Specifically, the central axes of the mounting plate 100, the first connecting seat 102, the connecting rod 205, the second connecting seat 2051 and the dust curtain 300 coincide with each other, so that the forces are balanced, which is conducive to the stability of the structure.

[0031] It should be noted that the positive thread 2011 and the negative thread 2012 have the same length and are symmetrically arranged about the central axis of the mounting plate 100. There are two nut seats 202 in total, and the two nut seats 202 are symmetrically arranged about the central axis of the mounting plate 100, ensuring that the starting positions of the two nut seats 202 are symmetrical and the running distances are the same, thereby ensuring that the lifting mechanism 200 can operate smoothly.

[0032] Specifically, there are a number of dust reduction rubber strips 302, and the several dust reduction rubber strips 302 form a four-layer curtain, which can effectively scrape coal and absorb dust. The dust reduction rubber strips 302 are made of wear-resistant rubber material and have a long service life.

[0033] Working principle: When the lifting dust curtain is used, first, the dust curtain 300 and the connecting rod 205 are fixedly connected by bolts, and then the mounting plate 100 is fixed directly above the conveyor belt by bolts, and then the screw 201 is rotated forward or reversely, and the nut seat 202 is limited by the upper lifting rod 203 and the lower lifting rod 204 and cannot rotate together with the screw 201. At this time, the two nut seats 202 move towards or in the opposite direction along the positive thread 2011 and the reverse thread 2012, thereby driving the upper lifting rod 203 and the lower lifting rod 204 to extend or contract, and then driving the dust curtain 300 to descend or rise, until the distance between the bottom end of the dust reduction rubber strip 302 and the conveyor belt reaches the set value, that is, the lifting and lowering adjustment of the dust curtain 300 is completed. The lifting dust curtain has an advanced design, a compact structure and is easy to use. By providing a screw 201 with a positive thread 2011 and a negative thread 2012 and two nut seats 202, rotating the screw 201 can cause the two nut seats 202 to produce a large displacement, thereby driving the upper lifting rod 203 and the lower lifting rod 204 to move toward or in the opposite direction along with the two nut seats 202, which is conducive to flexibly and quickly adjusting the height of the dust curtain 300 to meet actual needs. By providing a dust reduction rubber strip 302, it is possible to scrape off the coal that is too high on the conveyor belt, and to better absorb the dust generated in the process of scraping the coal, thereby greatly improving the working environment.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
